Document Summary

Muscle strength: muscle strength can be measured in one of 3 ways. Isometric: the muscle stays the same length. Isokinetic: the muscle changes length at a constant speed. Isotonic: the muscle maintains a constant force. Isokinetic strength is a bit of an artificial activity,, usually controlled by an isokinetic dynamometer: but it is a useful way to qua(cid:374)tify . Isotonic strength: really (cid:449)here it"s at, the (cid:449)eight does(cid:374)"t (cid:272)ha(cid:374)ge duri(cid:374)g the a(cid:272)ti(cid:448)ity, so the (cid:373)us(cid:272)les are produ(cid:272)i(cid:374)g (cid:374)early constant. It"s really (cid:449)hat you"re trai(cid:374)i(cid:374)g (cid:449)ith resista(cid:374)(cid:272)e trai(cid:374)i(cid:374)g force during a rep: as close as it gets to how you would perform a task in the real world. Muscle power: with muscle power, the goal is to increase both strength and speed. Muscle endurance: ultimately regulated by the cardiovascular system (how much oxygen can be transported to working muscles, as endurance improves, heart and lungs get larger and more efficient, example training for a marathon.
